On November 17, 2025, the Drug Enforcement Administration (DEA or Government) issued an Order to Show Cause (OSC) to Irina Gross, D.P.M., of Chagrin Falls, Ohio (Registrant). Request for Final Agency Action (RFAA), Exhibit (RFAAX) 1, at 1, 4. The OSC proposed the revocation of Registrant's Certificate of Registration No. FG2593487, alleging that Registrant's registration should be revoked because Registrant is “currently without authority to prescribe, administer, dispense, or otherwise handle controlled substances in the State of Ohio, the state in which [she is] registered with DEA.” Id. at 2 (citing 21 U.S.C. 824(a)(3)).

The OSC notified Registrant of her right to file a written request for hearing, and that if she failed to file such a request, she would be deemed to have waived her right to a hearing and be in default. RFAAX 1, at 2-3 (citing 21 CFR 1301.43). Here, Registrant did not request a hearing, and the Agency finds her to be in default. RFAA, at 1.^[1] “A default, unless excused, shall be ( printed page 38017) deemed to constitute a waiver of the registrant's/applicant's right to a hearing and an admission of the factual allegations of the [OSC].” 21 CFR 1301.43(e).

Further, “[i]n the event that a registrant . . . is deemed to be in default . . . DEA may then file a request for final agency action with the Administrator, along with a record to support its request. In such circumstances, the Administrator may enter a default final order pursuant to [21 CFR] 1316.67.” Id. 1301.43(f)(1). Here, the Government has requested final agency action based on Registrant's default pursuant to 21 CFR 1301.43(c), (f), 1301.46. RFAA, at 1; see also21 CFR 1316.67.

Findings of Fact

The Agency finds that, in light of Registrant's default, the factual allegations in the OSC are deemed admitted. According to the OSC, effective June 11, 2025, the State Medical Board of Ohio suspended Registrant's Ohio Doctor of Podiatric Medicine (DPM) license and Registrant's Ohio Respiratory Care Professional (RCP) license. RFAAX 1, at 2.

According to Ohio online records, of which the Agency takes official notice, both Registrant's Ohio DPM license and Ohio RCP license are permanently revoked.^[2] eLicense Ohio Professional Licensure License Lookup, https://elicense.ohio./​oh_​verifylicense (last visited date of signature of this Order). Accordingly, the Agency finds that Registrant is not licensed to practice podiatric medicine nor respiratory care in Ohio, the state in which she is registered with DEA.^[3]

Discussion

Pursuant to 21 U.S.C. 824(a)(3), the Attorney General is authorized to suspend or revoke a registration issued under 21 U.S.C. 823 “upon a finding that the registrant . . . has had his State license or registration suspended . . . [or] revoked . . . by competent State authority and is no longer authorized by State law to engage in the . . . dispensing of controlled substances.”

With respect to a practitioner, DEA has also long held that the possession of authority to dispense controlled substances under the laws of the state in which a practitioner engages in professional practice is a fundamental condition for obtaining and maintaining a practitioner's registration. Gonzales v. Oregon, 546 U.S. 243, 270 (2006) (“The Attorney General can register a physician to dispense controlled substances `if the applicant is authorized to dispense . . . controlled substances under the laws of the State in which he practices.' . . . The very definition of a `practitioner' eligible to prescribe includes physicians `licensed, registered, or otherwise permitted, by the United States or the jurisdiction in which he practices' to dispense controlled substances. 802(21).”).^[4] The Agency has applied these principles consistently. See, e.g., James L. Hooper, M.D.,76 FR 71371, 71372 (2011), pet. for rev. denied, 481 F. App'x 826 (4th Cir. 2012); Frederick Marsh Blanton, M.D.,43 FR 27616, 27617 (1978).

According to Ohio statute, “[n]o person shall knowingly obtain, possess, or use a controlled substance or a controlled substance analog,” except “pursuant to a prescription issued by a licensed health professional authorized to prescribe drugs if the prescription was issued for a legitimate medical purpose.” Ohio Rev. Code Ann. §  2925.11(A), (B)(1)(d) (West 2025). Further, a “ `[l]icensed health professional authorized to prescribe drugs' or `prescriber' means an individual who is authorized by law to prescribe drugs or dangerous drugs or drug therapy related devices in the course of the individual's professional practice.” Id. § 4729.01(I). Ohio statute further defines an authorized prescriber as “[a] physician authorized under Chapter 4731. of the [Ohio] Revised Code to practice medicine and surgery, osteopathic medicine and surgery, or podiatric medicine and surgery.” Id. § 4729.01(I)(5). Additionally, Ohio law permits “[a] licensed health professional authorized to prescribe drugs, if acting in the course of professional practice, in accordance with the laws regulating the professional's practice” to prescribe or administer schedule II, III, IV, and V controlled substances to patients. Id. § 3719.06(A)(1)(a)-(b).

Here, the undisputed evidence in the record is that Registrant lacks authority to practice podiatric medicine and respiratory care in Ohio. As discussed above, an individual must be a licensed health professional authorized to prescribe drugs in order to handle controlled substances in Ohio. Thus, because Registrant is not a licensed health professional authorized to prescribe drugs in Ohio and, therefore, is not authorized to handle controlled substances in Ohio, Registrant is not eligible to maintain a DEA registration. Accordingly, the Agency will order that Registrant's DEA registration be revoked.
